Garmin GSD 28 Sonar Module

Take your sport fishing to extreme depths with the Garmin® GSD™ 28 Sonar Module, a high-powered sonar module with features to improve your chances for success (transducer-dependent). Garmin RapidReturn™ sonar provides quicker returns on your chartplotter with 2 to 6 times the ping rate of our GSD 26, so you see fish before you're out of range (transducer-dependent). This Garmin sonar lets you easily distinguish bait from sport fish and get the clearest sonar reading thanks to next-generation xCHIRP technology. The Garmin GSD 28 Sonar Module supports a wide range of Garmin and AIRMAR® transducers (not included) that can be manually or automatically configured. When the seas get rough, ensure flat bottom returns with the MSC™ 10 external heave-compensation sensor (not included).
